5 Claims. 1

The present invention relates to the construction of dual or combination windows in which the regular or standard window is combined with a supplementary storm window so that the two windows may be connected and movable in unison. It is one of the purposes of the invention to combine the two windows in such manner that the inner and outer surfaces of the main window and the inner surface of the storm window are accessible for cleaning from within the building.

It is also an object of the invention to combine a main window and a storm window in such fashion that in all positions of adjustment they are not readily moved but will remain in the position in which they are placed against the force of the wind, and will not rattle. It is a further object of the invention to improve upon the means by which the windows are connected for joint movement.

These and other purposes will be evident from the description of the invention, it being understood that details of the construction are not essential and may be varied within the scope of the invention as set forth in the claims.

In the drawings:

Fig. 1 is an elevation of a window of the improved design, this view being taken from within the building and being in partial section.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal section through the combined window in closed position.

Fig. 4 is a similar view showing the window in open position.

Fig. 5 is a section through the connection between the main and storm windows on the line 55 of Fig. 3.

Fig. 6 is a section on the line 6-6 of Fig. 5.

In the drawings the main window frame is indicated by the numeral I and the movable casement or window by the numeral 2. In the embodiment of the invention shown, the movable casement is flanked by two supplementary, fixed easements, indicated by the numeral 4.

The movable main casement 2 is provided with facing strips 5 set in and attached to the upper and lower rails of the casement, these strips projecting laterally beyond the casement on the side thereof which is to form the axis of swinging movement. In the projecting ends of the strips 5 are located pins 6, about each of which is wrapped the double leaf spring 8 having the two spring arms 9 and I0 shown in Fig. 4. When the easement is closed, the extensions of the strips 2 and the pins 6 are received in recesses H in the frame. (See Fig. 1.)

The upper and lower sills of the frame are routed out to form channels l2 and in that portion of each channel I2 to the right as shown in Fig. l, is seated the metal channel or lining M in which the pins 6 and the double leaf spring 8 are movable. It will be noted that the shorter and stronger arm I 0 bears against the outer wall of the channel which serves to form the window into tighter engagement with the frame.

In the opposite or left hand end of the channels i2, as viewed in Fig. l, are secured the spacer blocks I6, to the outer surface of which are attached the bearing plate [1. Located at the top and bottom of the movable casement are links I8, each of which is pivoted to the adjacent strip 5 at the point 20. The other or far end of each link carries a pivot pin 22 which is received in recesses in the strip l1 and the block It.

At the free edge of the casement and located in the vertical stile remote from the hinge is a latch member 25. When the window is opened the hinge points formed by the pins 6 move outwardly along the channels M while the links I8 cause the casement to swing outwardly. In the position shown in Fig. 4, the window is at approximately its maximum open position. At this position, the inner and outer surfaces of the main casement can be reached from the interior of the building, as may the inner surface of the sup plementary or storm window. The sliding-pivotal movement of the inner casement also prevents any interference between the two easements.

The supplementary or storm window is indicated by the numeral 28. It is mounted in a supplemental frame 30 placed in the window opening, in the form shown there being provided stationary windows 32 on either side of the movable storm windows. The storm window is mounted on hinges 33 on the same side of the easement as the movable hinges 6.

It is desirable to connect the main casement '2 and the storm casement or window 28 by means which will not only insure that the two easements move in unison but also that they are held against rattling and against independent movement. When the two easements, mounted and connected in the manner shown, are in any open position, they mutually brace one another so that they one; a substantial resistance to wind pressure and will not easily move to any position other than that in which they may be moved by the householder.

The connecting means for the two movable the vertical stile of the main casement. This detail of the plate 4| serves as a means for properly locating the plate transversely of the stile.

The connection consists of a horizontal armii 48 in the outer end of which is secured the pin 45. The inner end of arm 48 is provided with a clevis traversed by a verticalpivot pin 50. In

this :clevis, and received on the pin 50, is an extension 5| projecting from a larger body 52 which is received in a recess or chamber 53 in the frame of the storm casement 28. The extension 5i is movable vertically in a slot 55 out in an escutcheon plate 56 which covers the chamber 53. A washer plate 58 is located between the end of arm 48 and the plate 55. On the other side of I the plate 56 is a second smaller washer 59 and between the washer 59 and the inner end of the member 52 is a coil spring 60, which yieldingly draws the arm 48 against the washer 58 and the latter against the face of the escutcheon plate 56.

When the connector 48 is latched in the position shown in Figs. 5 and 6, the connector is in the lower end of the slot 55. To disconnect the two movable easements, the entire connector 40 is moved upwardly, the extension 51 moving in the slot 55. On the rear of the plate 58 are stamped the two raised, roundedknobs 61 over which the washer 59 will ride, the spring 50 yielding to accommodate this movement. These projections or knobs 52 maintain the connec tor in raised or lowered position in the slot '55.

The spring connection contained in the assembly shown in Figs. 5 and 6 serves to draw the two easements together and to take up any looseness between them, thus avoiding all tendency to rattle. It also holds up the end of the connector when it is detached from the keeper 42, thus avoiding marring of the storm casement.

While the description of the various parts has been quite detailed, it will be evident that changes and modifications may be made therein without departing from the main features of the invention as set forth in the appended claims.
